Alliance Preps Improved Wi-Fi Security
Posted: 30th Apr, 2003 By: MarkJ
Broadband wireless LAN (Wi-Fi) Hotspots look set to benefit thanks to the introduction of a new Wi-Fi Protected Access (WPA) security specification:
WPA, a subset of the 801.11i WLAN security specification, is set to replace the creaky Wired Equivalent Privacy (WEP) scheme used by wireless clients and base-stations to encrypt data to date. 802.11i is due to be ratified as a standard by the IEEE next year.
WPA builds on WEP by offering a Temporal Key Integrity Protocol (TKIP), which constructs encryption keys in a more secure manner than WEP, which basically uses whatever you type in. WPA also uses the IEEE 802.1x wired and wireless protocol for authorisation and access control.
The Register reports that WPA-certified products will start shipping from next month (May).
